Do we have female characters having conversations that *are* specifically about men, or romantic relationships?
Yup and yup.
Although in the first case, it is usually done for comic relief, and often the men talk about the women in the same way and often at the same time. And it's hardly ever about romance (although some gender based teasing tends to be involved) but more about the usual men vs women gossip and in the gutter humor. Example from a few weeks or so ago...
Female 1: Did you see how Male 1 swings his hammer? That is so not the right weapon for him but he absolutely needed to have it.
Female 2: Because it is magical. Men love all things magical to boost their ego.
Female 3: He'll find a new toy eventually. Until then, we need to watch out so he won't accidentally hit us with it.
Female 1: Did you just make a HAMMER joke?
Female 3: *blushing* Uhh...
At about the same time elsewhere...
Male 1: Female 1 is sure flaunting that new necklace of hers around.
Male 2: It's because it's a magic one. Females love all things magic to appear more important. Or less insecure. Or both.
Male 1: And still she makes comments about my hammer.
Male 2, and 4 going on about hammer jokes
Talks about relationships usually are about one of them not wanting the other to do something dangerous, while of course the other doesn't want to be patronized. But it's usually a short lived discussion because it would get obnoxious to keep repeating it again and again. PCs not directly involved don't usually talk about the other PCs relationships. There may be some teasing every now and then, but talking about how to split loot or what to do next usually take up most of the in character talk
